SAFETY DEVICE roamea' on cans:

Application" filed March'14, 1925; Seria1tNoa15g626; Renewed "Auguste; 1928i r This invention relates to aisafetydevice its objectto provide a safety device-which-is adapted to be broughtelnto action automatically, soon as the fenderbar strikes against; a human body or-anyother object, to raiserthe front wheels from the ground; at: the same time stopping the operation of the driving axle and applyingabrake. action onto the rear wheels, thus effectively protectlng the human bodyor other ob]ect which has been passed under the upraise d front wheels ofthe vehicle.

A; constructional;-exampleof the subject matter of the "PIQSQllillllVGllillOl'l is illustrated in the accompanying drawin gs, in which Fig. 1 is a side elevation OftLI'IlOtOIzCflI' with its'body removed and showing the general arrangement of the devlce'accordrngz to this invention. w

Fig. 2 1s a plan thereof.

Fig. 3 is a detail of the ratchet mechanism.

Fig. 4 is a front viewithereof.

Figs. 5 and'6' are details ofthe'brake for the rear wheels.

Fig.;7 is afront view of1tlie-bracket as mounted on the frame.

The frame 1 of the vehicle is providedion bothsides with brackets 2*. J ournaled in said brackets 2 is a rod 14:, which is normally pressed downwardly by springs 3 provided at its ends. Secured to each end of the rod 4 is a leg or support 5 composed of three members of different length,

Brake legs 6 for the rear wheels are pivoted to the brake shoes or plates-7. Eccentric members 9 are secured to the rear axle case 8, and are connected with said brake shoes 7 by means of links 10. Said parts are so arranged that when the brake legs 6 fall to the position shown in dotted lines in Fig. 5 the brake shoes 7 are brought into frictional contact with the circumference of the rear wheel by a lever action. I

A pair of reels 11 which are spaced apart is mounted on a shaft 27 which connects the brackets 2 and between said reels is a reel 11. The reels 11 are connected by cables 15 to the legs 5, said cables passing over direction pulleys 15 The reel 11 is connected by a cable 15 with the legs 6, said cable passing over a direction pulley 15. For driving said shaft and said reels a ratchet 12 is provided, near the drivers seat, said ratchet be- Movable rod :16; carries-at its forward: end

a. fender ban or feeler v17 and 'is normally pushed forwardly byi'a. springld (see Fig. 3) mounted :ln'the, guide tube 19-. The rear portionofxthe movziblerod 16 is bent ups wardly and it engages with the latchr20f maintaining the latter in latching engages inent'with the teeth of the ratchet 12 The latch 20'isnpivoted at 20C Interposed: be tween'the engine: shaft and the driving axle;

is a frictionrclutch 21 :Which is released by the saidpeda l' 22 is 7 connected .bya cable 29 to the reel 111'; said depression of a pedal 22.,

cable passing over a direction pulley 22 the arrangement being such that the said :cable connected to: the pedal 22 is slaickened'when the legs 5: and (Sareflraised, on the contrary when'thex legs 5 and 6'are loweredrthe said: cableeonneotedto the pedal is tensioned'and'; the i'eetll thius pulling: the

wound around pedal'22;

Attached ito the brackets 2 are springs 23 adapted to engage with and absorb threshock oi the legsl5hwhen the-latter-are moved into upright positionas shown in full lines in Fig. 1. For this'purpose each leg member5 isprovided with an ear 24 adapted to be engaged by the springs 23. Pivoted to each of the brackets 2 is an auxiliary supporting leg 26 each of which is'connected by a cable-28 to one of the reels 11. A direction pulley 28 is provided for each cable 28. i

The operation of this invention is as follows: By operating the handle 1% the reels 11, 11 are rotated through the sprocket and chain drive 13, 13 so that'the legs 5 and (3 are normally held in their raised position as shown in dotted lines in Fig. 1. The pawl is normally held disengaged from the ratchet 12 of which the reverse rotation is normally prevented by means of the latch 20, the rear end of the latter being normally engaged by the upturned rear end 16 of the movable rod 16, as shown in Fig. Now, as soon as a human body or any otherobject is struck by the fender bar 17, the rod 16 will be moved rearwardly compressing the spring 18,

whereupon the rear portion of said rod 16 will release the latch 20 from the ratchet 12.

Thus, the legs 5, 6 and 26 fall, by the action of gravity, the free end of each leg standing on the ground. The legs 5 on falling down onto the ground will serve, co-operating with the frictional contact ofthe brake shoe 7 to the circumferential part of the rear wheel by a lever action, thus stopping the movement of the entire vehicle. In said operation, the ear 2% of the leg 5 will come into engagement 7 with the spring 23 and the latter serves to absorb any shock of thelegs 5. For releasing the legs, the reels 11 11 are rotated by operating the handle 14 so that first the legs 26, and then the legs 5 and 6 are raised into normal position, and the pedal 22 is released.

' The latch is then held in latching engage ment with the ratchet 12 by means of the rear end of the rod 16.

As willbe seen from theforegoing, according to the present invention, when the fender bar 17 strike against a humanbody or any.

other object, the front part of the vehicle is at once raised, at the same time the axle element, and a spring directly effective on the drive is interrupted, and a brake action is applied to the rear wheels, thus effectively preventing any traflic accident.

Having herein described our invention, what we claim and desire to secure by Letters Patent is i 1. A motorcar having a supporting leg,

connected to said fender element for allowing.

the leg to fall when the fender bar strikes against any object.

2. A motor car having a supportingleg normally held in raised position, a I'QGICOII? nected by a cable to said leg,'a brake shoe for the rear wheel, a second leg pivoted to said brake shoe and connected to said reel by a cable and normally held inraised position, a friction clutch interposedbetween the engine shaft and the driving axle, a pedal for actuating said Clutch, :1 cable connecting said pedal to the said reel. j v

3. A motor car having a normally inefii'ective supporting element to raise the front end of the car in an emergency, said supporting element being pivotally mounted on the car and provided with a plurality of a radially arranged legs of unequal length.

et. A motor car having a normally ineffective supporting element to raise the front end of the car in an emergency, said supporting element being pivotally mounted on the car and provided with a pluralityof radially arranged legs of unequal length, the pivot of said element being mounted for vertical movement, a spring to cushion said pivot and legs of said element to cushion the same.

In testimony whereof We aflix our signatures. a y
